RHEL or Red Hat Enterprise Linux is one of the many operating systems provided by Red Hat. Red Hat is a popular Linux OS and has started functioning ever since the mid-1990s. Red Hat earned a good reputation due to being stable, regularly updated, and reliable.
If you are using RHEL and want to find its version, this article is for you. Now let’s check 7 useful methods to know what version of RHEL you are using.
Method 1: Track Your System with Hostnamectl
The hostnamectl command helps track your system’s appearance on a network. It also finds the operating system and its release version. So, this can be a quick way to check this information.
To use this command, open a terminal and type:
$ hostnamectl
In the output result, you’ll see the OS, kernel, and the architecture details.
Method 2: Use RPM Command
Red Hat Package Manager, abbreviated to RPM, is a well known core package management utility included in Red Hat Enterprise Linux. You can identify the RHEL version you are using with this command.
Use RPM in the following manner.
$ rpm --query redhat-release
You can also identify CentOS’ (another OS offered by Red Hat) release version using the RPM command. To check, type:
$ rpm --query centos-release
As you enter the command suitable for your OS, the release version will appear on the screen.
Method 3: Check Red Hat Release File
Linux distributions based on Red Hat contain release files. You can find such files in the /etc/redhat-release directory. There are various types of Red hat release files, such as system-release, os-release, and redhat-release.
Check your Red Hat OS release version with the help of the below-given command.
$ cat /etc/redhat-release
To get more information, you can use the following commands.
$ cat /etc/system-release $ cat /etc/os-release #contains more information
Method 4: Check within Red Hat Issue File
To check your Red Hat version, check within the /etc/issue file. To find the version, type:
$ cat /etc/issue
Method 5: Use lsb_release Command
LSB stands for Linux Standard Base. The lsb_release command shows the Linux distribution information and some LSB. On RHEL, the lsb_release is provided within the redhat_lsb. You can simply install the redhat_lsb package to use the command. To install, type:
